Compact AC Tachometer Generators

The ATC DigiTec Division of Marsh Bellofram Corp. launched its highly compact 758-GF86/XF86 series of industrial open-face AC tachometer generators, part of its WESTCON product family. The tachometers are designed primarily for use on shaft ends to measure speeds of up to 100,000 rpm and extremely low torque burdens of less than 1 ounce-inch. Designed primarily for use by original equipment manufacturers, ATC DigiTec 758-GF86/XF86 series AC tachometer generators are speed transducers of the most basic form, consisting of simply a stator and a permanent magnet rotor mounted onto a rotating shaft within a customer’s own specified equipment.

Potted models (designated with the letter “P” in the type number) are also available with stator windings encapsulated within an epoxy material for greater protection. The compact size of the 758-GF86/XF86 series allows them to be installed in hard-to-reach areas such as gear boxes, diesel engines, and conveyor systems, saving space and reducing costs. As their rugged, bearing-free, and brush-free design requires no maintenance, they offer increased reliability and minimized downtime. (
